条件格式 API

FormatConditions.Add 基本用法

// 参数: Type, Operator, Formula1, Formula2
// Type: 1=xlCellValue, 2=xlExpression
// Operator: 1=Between, 3=Equal, 5=Greater, 6=Less, 7=GreaterEqual, 8=LessEqual

// 示例: 大于 90 的单元格标绿
var rng = ws.Range("B2:B100");
var fc = rng.FormatConditions.Add(1, 5, "90");
fc.Interior.Color = 0x00AA00;
fc.Font.Color = 0xFFFFFF;

// 示例: 等于"已完成"标绿，等于"逾期"标红
var rng = ws.Range("E2:E100");
var fc1 = rng.FormatConditions.Add(1, 3, '"已完成"');
fc1.Interior.Color = 0x00AA00;
fc1.Font.Color = 0xFFFFFF;
var fc2 = rng.FormatConditions.Add(1, 3, '"逾期"');
fc2.Interior.Color = 0x0000FF;
fc2.Font.Color = 0xFFFFFF;
var fc3 = rng.FormatConditions.Add(1, 3, '"进行中"');
fc3.Interior.Color = 0xFF8800;
fc3.Font.Color = 0xFFFFFF;

基于公式的条件格式

// 交替行斑马纹（用 xlExpression）
var fc = rng.FormatConditions.Add(2, 0, "=MOD(ROW(),2)=0");
fc.Interior.Color = 0xFFF0E0;

// 整行高亮（当 E 列="逾期" 时整行变红）
var fc = ws.Range("A2:Z100").FormatConditions.Add(2, 0, '=$E2="逾期"');
fc.Interior.Color = 0xCCCCFF;

清除条件格式

ws.Range("A1:Z1000").FormatConditions.Delete();

一键美化方案

当用户要求"美化表格"时，按以下标准执行：

function CL(c){var s="";while(c>0){c--;s=String.fromCharCode(65+(c%26))+s;c=Math.floor(c/26);}return s;}
var ws = Application.ActiveSheet;
var ur = ws.UsedRange;
var r1 = ur.Row, c1 = ur.Column;
var rEnd = r1 + ur.Rows.Count - 1;
var cEnd = c1 + ur.Columns.Count - 1;

// 1. 表头样式（首行）
var hdr = ws.Range(CL(c1) + r1 + ":" + CL(cEnd) + r1);
hdr.Font.Bold = true;
hdr.Font.Color = 0xFFFFFF;
hdr.Interior.Color = 0x8B4513;
hdr.HorizontalAlignment = -4108;
ws.Range(r1 + ":" + r1).RowHeight = 32;

// 2. 数据区域
var data = ws.((c1) + (r1 + ) +  + (cEnd) + rEnd);
data.. = ;
data. = -;


 ( r = r1 + ; r <= rEnd; r++) {
   ((r - r1) %  === ) {
    ws.((c1) + r +  + (cEnd) + r).. = ;
  }
}


 ( c = c1; c <= cEnd; c++) {
  ws.((c) +  + (c)). = ;
}
